Yeah, for me it's more of an issue where I'd like to know how various SCC's handle it, for the purpose of giving good advice to people considering to over-panel. Will likely keep saying, proceed at your own risk, contact the manufacturer to be certain for your specific case (since there are too many brands/models to keep a database on).
I'm aware of Victron's stance, I have a 250|100 and I've read that same section in the manual too, they imply is fine to over-panel, as it won't draw more than it can safely handle, but with MPP, it seems we don't know for sure. The other issue is, say MPP came back and said it was fine on a particular MPP model, that doesn't mean all MPP inverter models are the same, we know some of these companies use rebranded equipment from different manufacturers and products within their own lines may have different behaviors based on what branches they come from...
Me personally, I just won't exceed max Voc and max amps of the controller, and if I need more panels, I will just stack more inverters to get more PV inputs. It does cost more, but gives more redundancy and I could run even bigger equipment in my shop and stuff, that is why it is important to me to use stackable inverters so the system can scale out when you hit limits and want to grow it more. Plus your less likely to waste watts when you don't over-panel.
And in the meantime, I'll make it a point to not wire the PV inputs backwards.
